Overview
Shorter-acting boldenone ester. No pharmaceutical product has ever existed — exclusively produced by underground laboratories. Cypionate ester provides medium-duration release. Notable for post-injection pain (PIP) — boldenone cypionate is notorious in community reports for severe injection site reactions, likely due to the compound's tendency to crash out of solution at standard concentrations. Harm reduction: Same hematocrit monitoring as boldenone undecylenate. Start with small test injections to assess PIP severity. Low concentration preparations (200mg/mL or less) may reduce PIP.
Mechanism of Action
1-dehydrotestosterone derivative with cypionate ester for medium-duration depot release.
